Right now I have my LG LCD television on.
…which is hooked up to the Apple TV on the shelf below it.
…which is streaming Sherlock Holmes from a 5-year-old (white) MacBook running iTunes upstairs from my wife’s iTunes account via WiFi.
…which stores iTunes content on a external, Western Digital Passport hard drive.
…which I’m controlling via the Remote app on my iPhone 4.
If I were to go back in time and explain this to my 15-year-old self, this would have sounded not only impossible, but incredibly inefficient. But to my 35-year-old self right now? It makes perfect sense. And it’s all working seamlessly.
